Appearance:

Medium sized diving duck. Male with white sides and light grey,finely mottled back. Female mostly brown with prominent white feathering at base of bill (more white than most female Tufted Ducks), and often a pale cheek patch (sometimes missing in winter plumage). Large rounded head with no hint of tuft. Bill grey with much smaller, narrow, black nail than Tufted Duck. Wings with similar wing stripe as Tufted. Floats low in water.

Sound:

Male call carries only a few meters: a whistling "po-ho" last syllable slowly descending. Female calls with harsh "harr-harrr-harrr".

Appearance:

Small and agile gull with all black wing-tips, black legs (adults) and yellow bill. Area close to wing-tips much paler than rest of wings, and often visible at surprisingly long range (more so than the black tips). Adult winter with grey neck and black half-collar. Juveniles with black zig-zag pattern to wings, resembling pattern seen in Little Gull, Ross's Gull and Sabine's Gull. Differs from those in; no dark bar on secondaries, underparts of wing white, back grey, black on primaries reaches wing-tip. Flight action different from larger gulls; fast, stiff wing-beats and elegant maneuvering even in strong winds.

Sound:

Highly vocal at breeding ground. A mewing "kitti-wake", with the pitch rising on the second drawn out syllable, and then falling. Generally silent elsewhere, except when squabbling over food.
